High molecular weight linear products were regenerated after the ring-opening polymerization of the cyclo-products using potassium phenoxide as initiator.

Linear silicone fluid and aminosilicone monomer were used as raw materials in the synthesis of the instantly soluble aminosilicone fluid by alkaline polymerization.

PVA with low conversion had higher polymerization degree and linear degree as com- pared with PVA with high conversion;
